Manufactures only put a part in for a good reason. And the type of material used to make those parts. The GMC has 4 body mounts. 2 at the front, and 2 at the rear. The 2 main things that these mounts do. Is to keep the body, and frame as a unit. And keep 1. If you've ever taken a GMC completely apart. As I have. You've become very aware that the body is more of a main frame then the steel structure it sets on. We have 2 main steel structures. One at each end. To have something to attach drivetrain parts too. The 2 side rails have very little strength too them. I see them as a means of keeping the front/rear suspention structure. In position as to the relationship to each other. This is where the body pads come in. 2. There has to be a space between the body, and the suspention. To keep road vibration/noise away from the passenger area. These GMC's where built for a high end market. So whatever we use to make replacement pads. Shouldn't be any harder then the pads that GM supplied originally. Bob Dunahugh
